1 Road/Channel Relay Module (with light coupling) 12V

This module is a 1 Road/Channel Relay Module (with light coupling) 12V that meets the safety standard because it has an isolation groove between the control and load areas. It uses optical coupling isolation technology.

The triggering of this module is reliable and stable. It has a double FR – 4 circuit board design and a high-end SMT process. It also has indicators for power and relay operation. The relay terminals (C, NC, NO) are easy to wire up through screw terminals. The relay is safely driven by transistor BC547, which protects your input device, such as Arduino, from the relay circuit.

The inputs of this module are isolated to protect any delicate control circuitry.

It can be controlled by a wide range of microcontrollers, such as Arduino, AVR, PIC, ARM and so on.

The use of such high-voltage relay eliminates the risk of heating up of the relay as electromechanical relay limit the current consumption in accordance with a voltage rating.

Module interface:

The positive (according to the relay voltage VCC: connect power supply)
GND: connect power negative.
IN: relay module (effective) high-level trigger signal trigger end

Meaning of High level and Low-level

1. High-level trigger refers to using the anode voltage at the VCC connection way of a trigger and triggers the end when the trigger side has a positive voltage or to trigger voltage when the relay is off.
2. Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.

Features 

1. Equipped with high-current relay 10A@250VAC / 10A@30VDC.
2. It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc
3. High-quality screw terminals (Terminal Block) provided (C, NC, NO) for quick and easy connection.
4. A freewheeling diode to protect your microcontroller.
5. Input Signal Pin connected to Burg stick for easy accessibility.
6. LED status indicators to indicate the relay ON/OFF status.
7. Mounting holes provided
8. Signal input with a high-level signal, the common and often start conduction.
9. The relay can directly control all kinds of equipment and load.
10. One often opened a normally closed contact.
11. Blue KF301 terminal line more convenient.

1 Road/Channel Relay Module (with light coupling) 12V Overview

The 1 Road/Channel Relay Module (with light coupling) 12V is a single-channel switching board designed to drive AC or DC loads up to 10 A. It features optical coupling isolation and LED indicators for reliable on/off status, making it ideal for microcontroller-based automation of solenoids, motors, lights, fans and more.

Key Features of 1 Road/Channel Relay Module (with light coupling) 12V

• 12 V DC coil with high-current relay rated 10 A@250 VAC / 10 A@30 VDC
• Optical coupling isolation and PCB isolation groove for safe separation of control and load
• Screw-type terminal blocks for Common (C), Normally Open (NO) and Normally Closed (NC) connections
• Built-in freewheeling diode and BC547 transistor driver to protect your microcontroller
• Power and relay status LEDs for visual monitoring
• Panel-mounting holes for secure installation
• Genuine product, fast shipping from Zbotic across India

Applications and Use Cases

• Home automation: switch lights, fans or pumps via Arduino or Raspberry Pi
• Industrial control: drive solenoids, conveyor motors and actuators
• Robotics: control gripper or turret motors requiring isolated switching
• Remote power control in IoT prototypes and embedded systems
• Automotive electronics: turn on/off auxiliary lights, horns or fuel pumps

How to Use 1 Road/Channel Relay Module (with light coupling) 12V

Connect a 12 V DC supply to the module’s VCC and GND pins, then wire your control signal (e.g., from an Arduino digital pin) to the input signal pin—ensure grounds are common. Mount your load between the relay’s C and NO or NC screw terminals. When the input goes high, the BC547 transistor energizes the relay coil, closing the chosen contact and lighting the LED indicator.

Frequently Asked Questions

Can this relay module switch both AC and DC loads?

Yes, the relay contacts are rated for up to 10 A at 250 VAC or 30 VDC, allowing you to control both AC and DC appliances safely.

Is isolation provided between control and load circuits?

Absolutely. An optical coupler plus a dedicated isolation groove on the PCB separates the 12 V coil driver from the high-voltage load side to protect your microcontroller.

How do I connect the relay module to an Arduino?

Power the board with 12 V DC on VCC/GND, tie the module ground to the Arduino GND, then drive the input signal pin from any digital output. Wire your appliance between the C and NO/NC terminals, and the relay will switch when the input goes high.
